` This invention relates to the art pertaining to that type ofkonepiece shipping containers and board for making the saine having an the `United States', No. 1-,161,8l8,"granted to ine NoveiiiberQ, 1915; and air object isto provide improved blanks and containers of said type. n

"l `qo`called one-piece solid fiber board containers in current use-fare securedin set-up 1 or cubic form `bywire stitching or stapling.

j Heretofore," the use of wire stitchedboxes j inadeof faced cellular board has been found impractical for the vreason that the wire stitching or stapling b-reaks through" such facedcellular board so thatthe joint or seam` is insecure. i

.L "The use of gumnied tape for closing `the l* joints is not found perfectly satisfactory for j. the reason that said `tape is not desirably strong, and under wet conditions it is subject to become loosened and pulled away from theboard. j

i An object is to provide `a stronger construction offaced corrugated container and to avoid thedependence upon an `adhesive for holding the closed containertogether; and to make the seain of the faced "corrugated apart under wet conditions. j

\ An object of this inventionf is to provide :a double faced corrugatedboard container of suoli construction that all of its parts can container practicaliy proof against pulling W5 be fastened by wire stitching. j VAnOther object is to make a more perfect closure against the'ingress of insects, dust and'dirt; thus to make the container more acceptable for storage and shipment of loose raisins other products subject to injury j from contact`of,`or mixture with, dust or other foreign material. j j A f A feature of the inventionresides in the construction of the board andthe forming ofthe body out of five hinged panels, and the securing oftheiirst and fth panels togetherby mechanicalffastening means suoli as bywire stapling or stitching.

Theiinvention is applicable in various orms and in some cases may be embodied with corrugated board constructed with single ply faciiigs. Preferably indurated multiple ply facings are employed. induratedfacing strengthened f by al cellular "5 structure as. set forth in Letters-Patent of i ready for folding into cubical form. j

, The termlength herein 1s simply used to denote the dimensions along or parallel to the creases and is not indicativeofjcomparative dimensions.

The terms top andbottom where used in the specification refer simply to the top and bottomof theyiewsin the drawing and lnot to the complet-ed container. The term closure `willbefused to designate 75 thick"still1 leavesserviiig to partly or fully close the ends ofthe completed container.

A feature ofthe inventionV is the provision of `closures having relatively thin flaps formed `by anjouter skin and adapted to be 80 fastened to an adjacent closure.

Other objects, advantages and features of invention may appear from the accompanying drawing,` the subjoined detailed descriptionand the appeiidedclaiins. j l

Fig. 7 is an enlarged fragmental longitudinal section on line W7-m7, Fig. 6, of a container constructed in accordance with this invention so far as the same is applicable to a container formed of a blank having only single ply internal and external facings.

y Fig. 8 is an enlarged fragmental transverse section on line 038-908, Fig. 6 of a container analogous to that shown in Fig. 7.

The container in Figs. 1-.6 is composed of a .creased and slotted bent-up one-piece blank with outer skin ertensions and suitable stitching or stapline. y Y

The creased and slotted blank comprises a line of four body panels 1, 2, 3, 4, and a termina'l stitching panel orA lap 5, ofv equal length. YSaid blank is composed of three sheets cemented together face to face and forming an outer facing skin 6, inner facing or liner 7 and a corrugated filler 8 between the facings; and the double faced cellular board is thus made of such stiffness and strength as may be required.

The blank has four transverse and two longitudinal creases on its inner side, there being three transverse creases 9 to afford flexible lines permitting the blank to be bent with the skin 6 outside; the corrugated filler being crushed along the creases so that the blank material at the creases forms hinges between adjoining panels 1, 2, 3, 4; and a corresponding crease 10 between the fourth panel 4 and the stitching lap 5, serves in the same manner to hinge panel 4 and the lap 5 together.

At opposite ends of the panels 1, 2, 3, 4, there are provided two lines Y of bottom closures 11, 12, 13 and 1 4 and top closures 11', 12, 13 and 14 ,and the blank material at the longitudinal creases 15 like that at the transverse creases 9 and 10, lits the sheet material for hingedly connecting the panels and the closures together.

The blank is provided with slots 16, 17, 18, extending from the longitudinal creases 15 to the edges ofthe outer indurated facing 6 which extends outward beyond the outer edges of the closures to form flaps 19, 20, and 21, for .the first, second and third closures 1l, 12, and 13, and 11, 12 and 13 that are at the ends ofthe first three panels.

The skin G does not extend beyond the edges of the closures 14, 14', which may be termed stub4 closures, while the closures 11, 12, 13,

.purpose of aifording and 11, 12, 13 may be termed the flap closures.

In the form of double faced corrugated board shown in Figs. 1-6, the outer facing or skin 6 is made of three plies a, ZJ, c, and the inner facing 7 is formed of two plies ci and c, and in practical use, when the container is formed in a manner that is obvious from the drawing, and analogous to that known to the box makers art, bringing the closures 11 and 125 toward each other into closing position, the sealing -flaps 19, 20, 21, of the skin are overlapped and are then secured by the stitching 22 which is effected by the operation of the usual stitching machine, well known in the art of stitching solid liber board containers.

In the form shown in Figs. 7 and 8, the double faced corrugated board is made with single'sheet outer and inner facings as shown at G and 7 and it is understood that where it may be desired,the outer skin sealing flaps 19, 20, 21, may be cemented on the outer sides of the closures 11, 12, 13; but that for greater strength of package, the thicker multiple ply external facing or skin is preferred for the greater strength for packing fragile ware or goods or materials that are likely to be crushed when packages having heavy contents are piled in tall columns.

1n practical manufacture the inner indurated sheet 7 and corrugated sheet 8 for the blanks are stamped or cut out by a suitable die, not shown, in a manner which will be well understood by those skilled in the art; and the outer indurated sheet or skin 6 may be readily stamped or cut out by a die, not shown, which die conforms to the outer skin sheet G, including the six flaps 11, 11', 12, 12', 18, 13, as shown in Fig. 1. Then the three sheets will be cemented together to form the blank shown in Fig. 1, and the blanks are then ready for use and may be baled and shipped in quantities to the place where they are to be assembled and used. 1n common practise it is deemed preferable to stitch the stitching panel to the panel 1 at the factory and then ship the product as knocked dow-n containers to the place of use, where they will be set up as hereinbefore explained, and their flaps or closures cemented or stitched together.

The method of assembly will be readily understood by those skilled in the art, it being simply necessary vto first bend the blank at the hinge creases 9., 10, to form a hollow prism, with the stitching panel or lap inside as indicated in Fig. 5; and then the stitching lap panel 5 will be stitched to. the end panel 1 in any suitable manner as indicated at 22 in Fig. 5, and the flaps will be sealed by stitching, or with any suitable cement, and the package is completed.

l-n practise, the creased and slotted board is set up into cubical form by first bringing the body panels 1, 2, 3, 4, the stitching panel 5, and the closure panels into the form of a prism, rectangular in cross-section, and open at both ends, then fixing the stitching panel 5 and the first bodypanel 1 together by the stitches 22. Then the closures 11 and 13, and their flaps at one end of the prism will i l j j which comprises a corrugated or cellular fillbe folded toward each other and with the closures arranged to extend transversely at right anglesto the panels. Theclosures 14 lwill be folded oveiin like manner, and the closure 12, and its flap and the closure 14 will be folded into the prism form at right angles thereto and closure 14 will be folded to bring the edges of the closures 12 and 14 adjacent to, or in abutment against each other. j

The bottom flaps'20` formed of the outer indurated facing or skin 6 are brought across the closure 14 and stitched or cemented therea, Fig. 5, is then completed, ready to be charged with the approved commodity; and there- `upon the top closures will be folded in the manner abovedescribed and the Hap 20 will he stitched or cemented to the closure 14. i

Thestitching may be readilv effected by `a well known wire stapling machine, not shown, having a flat, thin clinching anvil arm, not shown, adapted to be inserted between the folded stub closure14 or 14 and the flap closures as 11 and 13, or 11 and 13,

j thus completing the filled package.

In the formillustrated in Fig. 7, the stitching panel or lap 5 is omitted and the panelV `4,is made `wider than the panel 2 so as to `extend over `the edge of, and terminate flush with the outer face ofV panel 1, and the joint is there secured and sealed with a `strip of guinmed tape, 22.

The panels 1, 2, 3, 4,` go to make up the four walls of the completed hollow prism, and the closures 11, 11', 12, 12, 13, 13, 14 and 14 form end extensions of the panels preparatory to folding over of the closures to close the ends of suchprism, and the outer skin facingis effective in forming flaps extending from closure edges for the purpose of sealing the completed prism ends by securement of opposite closures to each other through flap means.

Preferably, for the greatest security against breakage of seams and exclusion of ingress at the joints, the surfaces of the blanks which contact with each other are Y sealed with sodium silicate cement; and since it is customary to use such substance in the i cementing together of the corrugated filler `through the container walls made up of the j included in the completed construction hereinset forth; ,j i i l ,I claim z,-
